It may seem crazy that the value of Y > 5 can be anything, but it can be. Y greater than 5 basically means that Y is any number over 5 and has no exact value.

Answer:

$76

Step-by-step explanation:

Peralta and Amy worked last winter shovelling their neighbour's driveway.

Let the amount

Peralta earns = x

Amy earns = y

Amy earned $8 more than twice the amount earned by Peralta.

y = 2x + $8

y = 2x + 8

If their earnings totalled $110,

x + y = 110

x = 110 - y

We substitute 110 - y for x

Hence:

y = 2(110 - y) + 8

y = 220 - 2y + 8

Collect like terms

y + 2y = 220 + 8

3y = 228

y = 228/3

y = 76

Since, the amount Amy earns = y

Therefore, Amy earned $76

Answer:

63sq. meters

Step-by-step explanation:

The Surface area of the pyramid = 2B + ph

Base area B = 1/2 * 2 * 1.5

B = 1 * 1.5

B = 1.5m²

Perimeter of the base = 2 + 1.5 + 2.5

p = 6m

Height of the priscm = 10m

Substitute into the formula;

TSA = 2(1.5) + 6(10)

TSA = 3.0 + 60

TSA = 63sq. meters

Hence the surface area is 63sq. meters

how do u get it?

you know it is 80% of the students went for try out so you do 100% - 80% give you 20% students the number of students in the team already. so you do 20 / 100 x 110 students which already in the whole school over 1 which would give it 22

Answer:

C = 12 pi

Step-by-step explanation:

The radius is 6

The circumference is given by

C = 2 * pi *r

C = 2 * pi *6

C = 12 pi

Answer:

12π

Step-by-step explanation:

the circumference of the circle can be found using the formula: 2πr.

RW is the radius, and we know that RW=6, so we can plug this into the formula:

C=2πr

C=2π(6)

C=12π

so, the circumference of the circle is 12π.

Answer:

∠ A = 42°

Answer:

Step-by-step explanation:

A mutiple is found by taking a number and multiplying it by 1, 2, 3, 4, etc. This ensures us that that number will go into each of the numbers we find...or in other words, is a multiple. Choice A gives us 4, 8, and 16. Since 4 * 1 = 4, 4 is a multiple of 4; since 4 * 2 = 8, 4 is a multiple of 8; since 4 * 4 = 16, 4 is a multiple of 16.

Answer:

a) 4,8 and 16

Step-by-step explanation:

mmultiples of four are numbers that can be divided by four exactly

16/4 equals 4

8/4 equals 2

4/4 equals 1

Answer:

B.$1,150

Step-by-step explanation:

Given data

Weekly earning= $250

commission= 10%

Sales= $14000

Hence the expression for his total earnings per week is

y= 0.1x-250

x= sales

y= total earning

y=0.1*14000- 250

y= 1400-250

y= $1150

Answer:  300 cans

Step-by-step explanation:

Questions wants to know what her goal was:

When Sasha collected 180 cans, she reached 60% of her goal. This means that 180 is 60% of the goal that she set for herself.

To find this goal, assume that it is denoted as x. In such a case, the goal would be expressed as:

180 = 60% * x

x = 180 / 60%

x = 300 cans

Answer:

  a) 540°

  b) 720°

  c) 900°

  d) 1440°

Step-by-step explanation:

The total measure of internal angles of a convex polygon is given by the formula ...

  sum of angles = 180°(n -2) . . . . for an n-sided polygon

So, you count the sides, subtract 2, and multiply that result by 180°.

__

a) 180°(5 -2) = 540°

b) 180°(6 -2) = 720°

c) 180°(7 -2) = 900°

d) 180°(10 -2) = 1440°

Answer:

200% of 7.50 is 15.00

200% more than 7.50 is 15 + 7.5 = 22.50

Step-by-step explanation:

100% of 7.50 is 7.50

another 100% is 7.50

so 200% is 15.00

200% of a value is the value multiplied by 2

200% more than 7.50 is 15.00 + 7.50 = 22.50

The value of 200% more than $7.50 is,

⇒ $22.50

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

To find 200% more than $7.50.

Now, We get;

200% of $7.50

200/100 x $7.50

2 x $7.50

$15

Thus, 200% more than 7.50 is,

⇒ $15.00 + $7.50

⇒ $22.50
